Why Are Viruses Called Obligate Intracellular Parasites
Why Are Viruses Called Obligate Intracellular Parasites. Some authorities employ the word ‘grow’ for reproduce. They utilize the host cell machinery for their replication.

Certain protozoa such as trypanosoma spp., plasmodium, and toxoplasma; Why are viruses obligatory intercellular parasites? It encloses a single type of nucleic acid, either dna or rna.
Some Authorities Employ The Word ‘Grow’ For Reproduce.
Viruses are acellular entities and can only perpetuate inside a living host. Why are retroviruses considered a special class of viruses? They must use a host cell’s amino acids to synthesize proteins;
Viruses Are Small Obligate Intracellular Parasites, Which By.
They must use a host cell's amino acids to synthesize proteins. Viruses are obligate intracellular parasites because can reproduce only within a host cell, never on their own. Viruses are obligate intracellular parasites because can reproduce only within a host cell, never on their own.
They Must Use A Host Cell's Nucleotides For Transcription And Replication.
They must use a host cell's metabolic enzymes and pathways to obtain energy. Why are viruses obligatory intercellular parasites? They can live only inside the host cell.
Able To Exist Or Survive Only In A Particular Environment Or By.
Why are viruses called obligate intracellular parasites. See concept 19.2 (page 399) they must use a host cell's ribosomes to synthesize proteins, metabolic enzymes and pathways to obtain energy, amino acids to synthesize proteins, and nucleotides for transcription and replication. They utilize the host cell machinery for their replication.
Because Of These Limitations, Viruses Can Replicate Only Within A Living Host Cell.
That is, they lack metabolic machinery of their own to generate energy or to synthesize proteins, so they depend on host cells to carry out these vital functions. The rna animal viruses with the most complicated replicative cycles are the retroviruses (class vi). For propagation viruses depend on specialized host cells supplying the complex.
